Experts explained the peculiarities of left-handedness and warned against retraining.

      "The causes of left-handedness in children are varied: genetic predisposition, conditions during the mother's pregnancy, and the way neural connections develop. It is important to understand that this is a natural variant of development, not a defect," transsibinfo.com quotes a specialist in neurophysiology as saying.

      Experts warn against forcibly retraining left-handers. Such intervention can be harmful, since the brain has already adapted to a particular system of motor control. Forcibly changing this system can lead to stress, reduced concentration, increased fatigue, and even speech problems.

      Left-handers regularly encounter everyday difficulties, since many household items — from school furniture to kitchen tools — are originally designed for right-handers. However, the brain has a considerable capacity for adaptation, and the unconventional thinking of left-handers often contributes to finding original solutions in various situations.

      Long-established cultural norms and traditions, as well as the design of most tools, have long supported the dominance of the right hand in society.
